To aZZ whom it may concern.- 7

Be it known that 1, AUGUST SVENSON Hov- ANDER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful .Horseshoe-Calk, of which thefollowing is a structed and efificient calk for the same which maybeattached and detached when required to replace worn or broken calks orto change from'sharp to dull calks, or vice versa, as required, withoutremoving the shoes from the hoofs of the horse.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of embodiment of the invention capableof carrying the same into practical operation, it being understood thatthe invention is not necessarily limited thereto, as various changes inthe shape, proportions, and general assemblage of the parts may beresorted to without departing from the principle of the invention orsacrificing any of its advantages.

In the drawings thus employed, Figure 1 is a perspective View of ahorseshoe from beneath with the improved calks attached. Fig. 2 is adetached perspective view of the improved toe-calk. Fig. 3 is alongitudinal section through the toe portion of the horseshoe and theimproved toe-calk. Fig. 4 is a detached perspective view of one of theimproved heel-calks. Figs. 5 and 6 are detached perspective views of themodified form of the calk required for summer use. Fig. 7 is aperspective View illustrating another modified form of the calk.

The improved calk comprises a base member 10, having a shoulder 11 forbearing upon the body of the horseshoe, (represented at 12,) and withsharpened or dull bearingribs extending downwardly therefrom, as thecase may be, or accordingly as the device is used in winter or summer.

The base portion of the toc-calk is provided with spaced studs 13 14 forentering corresponding cavities in the body of the shoe 12, and the baseportion of the heel-call: is provided with a single stud 15 also forentering corresponding cavities in the heel portions of the shoe. Theseveral studs are provided, respectively, with lateral spurs 16 17,inclined to the longitudinal plane of the stud for hearing against thewalls of the cavities in the shoe and reversely to the line of movementwhich it is necessary to impart to the studs in removing them from thecavities, so that the spurs ofier a constant resistance to theaccidental removal of the calks.

The studs and their inclined spurs will fit the cavities in the shoe soclosely that they will require considerable force to insert them andwill not work loose while the shoes are in use, as the strains exertedupon them will at all times tend to hold them in the shoe, as will beobvious.

When the calks are to be detached, a light lateral blow upon the side ofthe shoe opposite the studs will loosen the calks sufficiently to permitof their withdrawal. Thus when in use the calks will remain rigidly inposition and will not become loosened or detached by any strains towhich they may be subjected, while at the same time they can be readilydetached when required for renewal or repairs or when it is desired tochange from the sharp to the dull form, or vice versa.

The sharp form of the toe-call: is clearly shown in Figs. 1, 2, and 3and comprises a central longitudinal rib 18 and transverse end ribs 19,the latter intersecting the central rib at the ends and forming bracesthereto, while at the same time effectually preventing lat eral slippingof the hoofs of the horse.

The heel-calks are wedge-shaped, as indi cated at 20 in Figs. 1 and 4,for winter use and in cylindrical form, as in Fig. 6, for summer use,and the toe-calk will also be made oblong in shape, as in Fig. 5, forsummer use.

The form of toe-calk shown in Figs. 1 and 2 isan important feature ofthe device, as its compound form efl'ectually prevents slipping bothforwardly and backwardly and sidewise or laterally and withoutincreasing the weight or cost of construction.

In Fig. 7 another modified form of the calk is shown, which may beemployed either as a heel or toe calk, as preferred. In this form isclaimed is- 1. As a new article, a horseshoe-calk having a stud forentering a corresponding cavity in the body of the horseshoe andprovided with a plurality of lateral spurs for bearing against the wallsof the same said spurs being inclined to the longitudinal plane of thestud.

2. As a new article, a horseshoe-call; having a stud for entering acorres tionding cavity in the body of the horseshoe and provided with alateral shoulder at the juncture of the 'calk and stud for bearing uponthe horseshoe adjacent to the cavity, said stud being provided with aplurality of lateral spurs inclined to thelongitudinal plane of the studand adapted to engage the walls of said cavity.

3. As a new article, a horseshoe-call: formed with a base portion forbearing upon the body of the horseshoe and having a central longitudinalrib with transverse ribs intersecting the longitudinal rib at oppositeends of the latter, and spaced studs extending from said base portionfor entering cavities in the body of the shoe said studs being providedwith a plurality of lateral spurs inclined to the longitudinal plane ofthe stud and adapted to engage the walls of said cavity.

4:. As a new article, a horseshoe-call; formed with a base portion forbearing upon the body of the horseshoe and having a central longitudinalrib with transverse ribs intersecting the longitudinal rib at oppositeends of the latter, said ribs being provided with cutting edges disposedat an angle to each other, and means for detachably connecting said basemember to the body of the shoe.

In testimony that I claim the foregoing as my own I have heretoafiixedmy signature in the presence of two Witnesses.

AUGUST SVENSON HOVANDER.
